April 2020 marks the 50th Anniversary of Apollo 13, a mission deemed "a successful failure" because of what NASA learned about rescuing crews, and more importantly, collaborating with other people during times of immense pressure.
The motto on the mission patch means "From the Moon, knowledge," and the three horses pulling Apollo's chariot symbolize bringing the light of knowledge to all people.
